Q1: slightly MESIAL
Q2: MESIAL cuspal ridge is shorter than the distal cuspal ridge r
SLIDE 28: PERMANENT MAXILLARY SECOND PREMOLAR –MESIAL
Q1: Which cusp tip is more pointed? (Lingual or Facial)
Q2: What’s unique about the facial cusp tip? (it’s relationship to the facial vertical line that marks the greatest facial curvature and the faciolingual long axis bisector of the crown).
The FACIAL cusp tip is more pointed than the lingual cusp tip. **
- The lingual cusp tip is more rounded.
Q2: The facial cusp tip is located about half way (btwn those two vertical lines). Right in the middle of the two.
Slide 29: PERMANENT MAXILLARY SECOND PREMOLAR –MESIAL
(Multiple Answer Question –be on the lookout to see which one’s correct)
Q1) The slants of the triangular ridges are ________ (more steep or not as steep) as those seen in the maxillary first premolar.
Q2) What does the mesial marginal ridge look like? (Is it curved or straight)?
Q3) The mesial marginal ridge is __________ (continuous or non continous) across the tooth.
- Is the mesial marginal ridge (divided or not divided) into two segments by a groove.
A1: NOT AS STEEP
A2: the mesial marginal ridge is almost HORIZONTAL across the tooth
A3: ** CONTINUOUS across the tooth. It is NOT DIVIDED into two segments by a groove.
Slide 30: PERMANENT MAXILLARY SECOND PREMOLAR —OCCLUSAL
